Application flied August 8, 1912. Serial No. 714,085.

To all whom it may concer/i Be it known that l, EDWARD B. BIRKEN- BEUEL, a citizen 'of the United States, and resident of Portland, in the county of Mult nomah and State of Oregon, hare invented certain vnew and useful Improvements in ChangeMaking Machines; and I do hereby declare the following to bea full, clear,v

and exactI description of the same, refer` ence being hadto the accompanying drawings, formingpart of the specification, and and 'letters of reference marked thereon.

This invention relates to key controlled actuating mechanism and, while the invention maybe utilized in key controlled shaft actuated mechanisms of various kinds, it is especially designed for .use in a change making machine, speciiicall y of the type illustrated in the application for patent filed by Thomas I. Potter onA June 24, 1911, Serial No. 705,868, other types of machines of this general character being illustrated in the Uhnerlatent No. 1,020,466', and in the- Potter Patent No. 1,011,845, to which pat ents reference may be had for a more lcomplete understanding of the coin handling or discharging mechanism not fully illustrated herein. Y

. The'objects of the invention are to. prorido an exceedingly simple and highly effi-V cient mechanism whereby the actuating shaft and parts actuated thereby may be coupled'togethcr and the uncoupling of the same controlled and the actuated parte locked by the keys or such keys as may have been operated in setting the machine.

llcferringto the accompanying drawings, Figure 1 is a perspective view of parts of a change machine adapted for setting or positioning the selector, the supporting frame and bearings being largely omitted, and certain of the parts heilig broken away and in section. Fig. 2 is a sectional elevation of certain of tlieparts shown in Fig.-1inthe positions assumed by them when the actuated part has been positioned and locked. Fig. 3 is a similar view with the part-s in normal position.

llike letters ofreferencc in the several figures indicate the same p rts.

Theessential features of the machine ma be briefiy stated to be an actuating sha t such asw A, an actuated mechanism which, in theV machine illustrated, Iembodies 'primarily a pair of segments B and C from which motion is communicated to other parts which will be hereinafter brieiiy referred to, a series of keys preferably arranged in sets or groups,- and indicated by the reference letters D, D, DJ and E, E2, E3, and a coupling mechanism which is adapted to couple' the actuating shaft and actuating vmechanism together, which coupling mechanism is disconnected andthe actuated mechanism locked by coperation with the keys.

In the preferred embodiment of the invention the actuating shaft A is provided with or adapted to move disks 12 conven iently rigidly mounted directly thereon and having concentric peripheral portions F, and recesses forming shoulders and f. Segments B and C are ournaled on the shaft A, and each segment is provided with a piv oted dog 10 haring a projection G adapted to enter the recess in the disk l2 and to cooperate with the shoulders and f so as to couple the actuating shaft .and actuated 'mechan'igm together for simultaneous movement. Springs such as g are ployed for insm-ing engagement of the dog with the shoulders, as well as to insure the release ofthe dog from engagement with the keys as will-be now explained. The keys D and E are preferably arranged in segmemy tal series in a frame or key carrier H of ordinary construction, and with their inner ends in position to project When operated into the path of a projection G on the dog, whereby when the dog advanced by thelacsf tuati'ngl shaft comes into contact with an operating key, as'for example, the key D7 in Figs. 1 and 2, it will be lifted out of its engagement with the disk 12, thereby disconnecting the actuating shaft from the actuated mechanism, and at the same time, the pivotal movement of the dog will move the projection G up into the space between the operated key D2 and the next preceding key as D. thereby securely locking` tlie actuf ated mechanism against angular movement .in either direction. lVhen the projection G is lifted out of the recess andthe disk 1Q continues its movement. the projection (i rides upon the concentric surface F of the 'l disk, whereby the dog is held in engagement with the keys until the disk again returns to a position where the projection G may.r drop into the recess, whereupon the disk, dog and actuated mechanism will be repreferably ems"- turned to noi-mal positions by the return .moi-'ement of the actuating shaft A.

The dog l is preferably provided with a projection G2 at its rear end which will ride 5 in contact with the concentric surface of the disk so as to limit the upward movement of the forvv'ard port-ion of the dog and serve as a means whereby the pivotal movement.

ofthe dog on the actuated mechanism ma be controlled from theperiphery of the disk lindependently of any other controlling means. 'I' he stems of the keys D and E', i etc., are preferably provided with coil spring 14, by which the keys are returned to normal position, and they are held in their operated' position by a sliding plate K which `engages teeth ,7c on the stems of the keys, it being understood, of course, that when one key is depressed it will release any other previously operated key in the well understood manner. ln accordance with the present invention, the release of previously operated' keys is insured by the provision of a second incline 13 on each key' stem above the tooth or projection 3, which incline 13 is of greater height than the tooth or proliection k and therefore when a key is operated and pressed downwardly below the position where it will be retained by the plate K, vit will impart a greater loiigitudinal movement to the plate K than would the projection c, and thereby insure the release of previously operated keys.

In connection with this machine,A it is desirable that the actuated mechanism shall be initially arrested if no key of the series controlling the same has been operated, and to accomplish this result there is provided what might be termed a Zero `key. This Zero key corresponds in construction to the keys D E, etc., except that it has no finger piece and is made relatively short. Such a key is shown at L in the drawings and is adapted to be operated or set by the return of the dog l0 to normal position, shown in Fig. 3. lVhen ,operated or set it projects into the path Iof the dog and will arrest the same during the initial forward movement, but the zero key will be released and withdrawn from the path of the dog by the ope-ration of any other key of the series. ln other words, the action of the zero key' is in all respects similar to that'of the other keys save that it is operated or set automatically. y

The means for operating the zero keys from the position shown in Figs. l and 2 to the-position shown in Fig. 3 preferably consists of a v vertically movable frame M adapted to overlie the ends ofthe keys L, as shown in Fig. 2. Said frame at its lower end is pivotally mounted' on the upper arms of'bell crank levers N, while the lower arms of said levers carry a bar il located Ain position to be struck by the dogs '10 when they return to normal position, whereby the bell ends of the frame, which coperate with projections or -aiitifriction rollers iV 2 on the iixed frame of the machine. y Suitable Springs such as m may be provided for moving the zero key actuating frame and bell crank.

from the position shown in Fig. 3 tothat.

shown in Fig. 2.

In operation, the desired keys of the se- .ries are depressed and will be retained in operated position as explained.4 The shaft A is rotated forwardly by means of the crank handle A', carrying with it the segments B and C, constituting the first portion of the actuated mechanism. Thev dogs 10, coming in conta-ct with the operated keys 'of the series of keys will be lifted out. of engage` ment with the disks l2 on the shaft A and will simultaneously lock between the adjacent keys so that no further movement of the actuated mechanism in either direction can occur, until the shaft Aand disk l2 turn to` a position where the dogs may again drop into the recesses of the disk.

The actuated mechanism illustrated in Fig. 1 corresponds specifically to the mechanism of the application first 'above mentioned, and while it forms no portion of the present invention, specifically considered, it may brieliy be described as a mechanism embodying a` selectorv O adapted to be positioned in two directions, to wit: longitudinally and angiilarly, one of the segments,

that lettered C being adapted to positionthe selector angularly, while the other of said segments B is adapted to position the'same longitudinally. To transmit thesel vso motions to the selector it is mounted to slide y longitudinally on its shaftO, but to rotate in unison therewith, and the shaft is. provided with a pinion o meshing with teeth n on the segment C. A carriage P mounted to slide longitudinally. on a guide p is adapted to coperate with the selector O for moving it longitudinally of'its shaft, and this carriage is connected by a iieXible. connection Q passing around an idler y, with the grooved periphery 7) of the segment B. whereby upon the rotation of the segment B the selector will be advanced along its shaft in proportion to the movement of the segmentf'and the return longitudinal movement of the selector is effected by a return spring such as l in Fig. l. The periphery of .the selector is suitably perforated or formed to control the movements of selector pins R which Llare advanced by a cam and roller Pf,

and said pins in turn through lever and arm connections, indicated at S in Fig. l; control the egectors for coins to he returned as a recess, and a series of et one of the projections being ;,fi tion never before attained. I do not wish to be understood, however, as limiting the invention to the particularl form of the oppositely arranged projections for it is obvious that the upper projection may be variously formed for .engagement with the operated key of the series and so as to eligectually lock the dog and actuated mechanism against further movement in either direction when the connection or coupling between the ac- 20 tuated mechanism and shaft is released by withdrawing the lower projection from the recess in the disk.

Having thus described my invention, what I claim as 1new and desire to secure by Let- 25 ters Patent of the United States, is:

l. In a shaft actuated key controlled mechanism, the combination with the acj tuating shaft, a disk rigidly mounted thereon and having a concentri periphery and independently operable keys, of a segment journaled on the shaft, a dog pivotally carried by the segment and having a pair of spaced. in- Wardly extending projections, one relatively 3.5 in front of the pivot and one relatively at the rear thereof, the projections extending toward the disk a distance suhcient for enabling both projections to ride in contact with the periphery of the disk at the same c time and one of the projections being adapted at times to extend into the recess whereby the other projection is moved from contact with the disk, said dog having a projection extending toward the keys and disposed to move in a path into which said keys are designed to be projected when operated, whereby said last named projection is adapted to engage an operated key when the shaft is actuated for lifting the notch,-

engaging projection out. of the notch and thus leaving the shaft free to move angularly independently of the segment.

2. In a shaft actuated key centi-oiled mechanism, the conbination with the actuatl `ing shaft, a disk rigidly mounted thereon -and having a concentric periphery and a recess, and a series of independently operable keys, of a segment journaled on the shaft, a dog pivotally carried by the segment and havsu ing a pair of spaced, inwardly extending proh jections. the projections ente -ding toward the disk a distance sufficient for enabling both projections Ato ride in contact with'the pc: ripnery or disk at the time and l A .J capter., at tintes to extend into the recess whereby the other projection is moved from contact with Athe disk, said dog having a projection extending toward the keys and disposed tu more in a' path into which said keys are designed to be projected when ope-rated, whereby said last named projection is adapted to engage an operated key when t-he shaft is actuated for lifting the notch-engaging projection out of the notch and thus leaving the shaft free to move angularly independently ot' the segment.

3. In a shaft actuated key controlled mechanism, the combination with the ac y tuating shaft, and a. series of independently operable keys, of a segmentjournaled ou the shaft, and means for transmitting movement from the shaft to the segment, said movement transmitting means being disposed to move in a path intersected by an actuated key, and said movement transmitting means being movable and adapted to be moved when brought into contact with an actuated key to a position between the actuated key and an adjacent noneactuated key Jfor being locked against movement in either direction.

4. In a shaft actuated key controlled mechanism, the combination with the actuating shaft, disk mounted rigidly thereon and having a concentric periphery andrecess in said periphery, and a series of independently operable keys, of a segment journaled on the actuating shaft in proximity to the disk, a dog pivotally mounted on the segment and having two oppositely arranged projections thereon, both` movable in unison toward and from the shaft, one fitting the recess in the disk, and the other conforming to the. space between adjacent keys of the series of keys, said last named projection being adapted to travel in a path intersecting the end of an operated key, whereby the dog will be released from its engagemen with the disk and moved into locking engagement between adjacent keys.

' 5. In a mechanism such as described. the combination with a series of finger keys and a zero key, means for retaining said keys in operated position, an actuating shaft and an actuated mechanism with -means for connecting the actuated mecha-- nism and shaft controlled by they keys, ot means for operating the zero kev,.when the actuated mechanism is returned tonormal position, embodying a bell crank lever with which the actua-ted mechanism coperates, a frame moved by said lever and coperating with the Zero key, and an incline for morirail .said frame out of engagement 'with i'iism such as described, the n the actuating shari. disk ecess 'ther Espas e1 ibis gieten?, may be obtaed''or operate by said bell crank lever and overf lyngthe zero key, and an incline and cooperating projection for moving said frame i out of line with the zero key lafter the letter is lmoved to its operated position.
